• Alanine aminotransferase (ALT) and aspartate aminotransferase. (AST) < 3 X ULN.

• Calculated creatinine clearance > 30 mL/min.

• Absolute neutrophil count (ANC) > 1,000/cmm and platelets > 75,000/cmm.

• Patient has a life expectancy of at least six months.

• Patients must be at least two weeks from major surgery, radiation therapy, participation in other investigational trials and have recovered from clinically significant toxicities of these prior treatments.

• Patients should be on stable doses of 6-mercaptopurine, methotrexate, vincristine and prednisone/dexamethasone as part of the POMP/D regimen, for a minimum of eight weeks PRIOR to starting ixazomib treatment.

• Agree to practice effective barrier contraception during the entire study treatment period and through 90 days after the last dose of study drug, OR

• Must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, OR

• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable methods of contraception.)

Exclusion criteria:

• Systemic treatment, within 14 days before study enrollment, with strong CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of ginkgo biloba or St. John's wort.

• Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, or psychiatric illness/social situations that would limit compliance with study requirements. Patients should not have evidence of active infection.

• Inability to swallow oral medication, inability or unwillingness to comply with the drug administration requirements, or GI procedure that could interfere with the oral absorption or tolerance of treatment.

• Active chronic graft vs. host disease requiring therapy.

• Patient has ≥ grade 2 peripheral neuropathy.

• Participation in clinical trials with other investigational agents not included in this trial, within 14 days of the trial start and throughout the duration of this trial.

• Evidence of current uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past six months.

• Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with treatment completion according to this protocol.

• Known allergy to any of the study medications, their analogues or excipients in the various formulations of any agent.
